The problems
Speed work that survives the next app.
App sprawl and leftover code make the product page slow. We make it fast and usable so search, AI, and a phone can actually buy from it, then stay so the next app doesn't undo it.
Why is my Shopify store slow?
Why is my Shopify store slow? You run the brand. A slow product page is one leak on the storefront. If that's the one costing money, we start here.
Usually the product page: too many apps, heavy images, leftover ghost scripts, a theme that ships everything up front. Home can look fine. Product is where people wait. That's not a different business from the store and Klaviyo not matching. Same theme. Same leftovers.
We start with what's public. The storefront scan is a speed and page-friction score. About a minute. It cannot see Klaviyo. That's on purpose.
Is Klaviyo slowing the store?
Is Klaviyo slowing the store? It can, if the script is duplicated or leftover ghost scripts are still shipping after an uninstall. That's leftover / ghost scripts in the theme, not a reason to delete Klaviyo.
What this actually is
How fast the main content shows up. How fast the page reacts when someone hits add to cart. Whether the layout jumps when an app injects late. On a product page that's usually the image, the apps, the theme shipping everything at once.
"Why is my Shopify store slow" is almost never mysterious. Too many apps. A theme that can't take the next feature without another app. Images without care. Klaviyo loaded twice. A speed app fighting the theme.
Lab numbers are a controlled run. Chrome field data is what people actually felt. The scan pulls both when they exist. That's the start. Not the whole job.
Not a speed app. Not a one-off pass.
Other tools defer scripts and call it a scan. If you want that shape, they already sell it. We change the theme and the app stack so there's less to defer. Then we keep doing that when marketing installs the next thing.
A freelancer PageSpeed pass is the other miss. They squeeze the lab score, hand you a report, leave. An app the following week puts the JavaScript back. Speed without someone who stays is a screenshot.
For broader stack guidance (which apps to install, skip, or replace at your revenue band), see the Shopify Systems Stack directory. Speed is one job. The stack is the full picture.
What we do on the store
- Start with the product page. That's where money waits.
- Retire leftover app code. Speed and a messy theme are the same files.
- One Klaviyo script. Duplicate onsite code is a speed problem and an email problem.
- Keep speed in the same help as the mismatch. A tracking fix shouldn't make the page worse. A speed fix shouldn't delete checkout tracking.
A slow product page after an app came off is how a lot of people get here. We fix the store-side of email, or a retainer if you want us finding the next leak. The retainer also covers the other leaks when that's the next one.
At Troop Themes, demo stores had to stay fast. That was a catalog bar, not a case-study number invented for this site. Same idea here: the storefront has to stay fast after the next feature, not before it.
What this is about
/audit is the tool: public speed and page issues, about a minute, saved link. This page is the job after that: speed that survives the next app, as part of what we own. Don't expect the scan to rewrite your theme. Expect it to show whether the public storefront is already in trouble.
Straight answers.
Usually the product page: too many apps, heavy images, a theme that ships everything up front. Home can look fine. Product is where people wait.
